This following important information must be read and understood by all users of Cygnus ultrasonic thickness gauges. The correct use of Cygnus ultrasonic thickness gauges requires identification of the correct equipment for the specific application coupled with an appropriately trained and qualified operator or technician.
The Gauge is able to operate accurately in adverse environmental conditions. The Gauge is a solid-state electronic instrument which, under normal operating conditions, will give many years of active service. To connect the TSR the Cygnus UW gauge must have an integral Impulse Connector fitted.
